I need help understanding how the practice questions work. I was working on some of the practice questions and my input and output matched the example; but it told me I was wrong. Can someone help me understand what I did wrong?

Problem = FLOW006

You’re given an integer **N**. Write a program to calculate the sum of all the digits of **N**.

### Input

The first line contains an integer **T**, the total number of testcases. Then follow **T** lines, each line contains an integer **N**.

### Output

For each test case, calculate the sum of digits of **N**, and display it in a new line.

### Constraints

- 1
**≤****T****≤**1000 - 1
**≤****N****≤**1000000

### Example

**Input** 3 12345 31203 2123 **Output** 15 9 8

My code:

numbers = input()

n = 0

for num in numbers:

x = int(num)

n += x

print(n)

input = 12345

output = 15
